UNITED STATES; PATENT OFFICE commons s'rsmuznn Samu-El Kali-Shalom, autun. Y. Application June 10, 1939, Serial No. 278,513 12 Claims.(01.21-93) This invention relates to an automatic sterilizer and moreparticularly to a sterilizer adapted for continuous operation.

The present invention provides a method and an improved means fordestroying small organisms and bacteria, and it is primarily intendedfor the treatment of materials to be used in the" manufacture andpreparation of cosmetics: but it is also applicable to many othermaterials, which either for purposes 01' preservation or as a sanitaryprecaution or other similar purpose in which it is desirable todestroyer inhibit the growth or development of deleterious germs or anyliving organism, by utilizing fluid pressure greater than the normalatmos Tieric pressure.

- Materials used in the manufacture of cos metics which containbacteria, spores or other living organisms are harmful and tend todiscolor the skin and in many cases cause the skin to become thin,wrinkled, dry, inelastic, and sub-' J'ect to uncomfortable irritation.

Therefore, the primary objects of the invention are to provide animproved method and means which shall be adapted for the sterilizing ofsubstances which consist, in subjecting such materials and substances todirect air pressure; to provide an improved method whereby the particlesof the different materials and substances are fed into the system inmass. form but are presented to be sterilized individually and forcedinto an air stream moving at a high speed and under great compressionalenergy; to provide an improved method and means whereby materials ofdifferent classes may be sterilized and freed of any living organismswhich may .get eventually into the pores of the skin and cause seriousconsequences; to provide an imdirection or in a direction opposite toeach other within the sterilizing chamber, so that the currents ofmaterials to be sterilized shall sweep one against the other; to providean improved apparatus having a plurality of air streams arranged -tooperate in the-same or opposite directions to produce a more efficientsterilizer; and

proved method whereby the difierent materials used in the manufacture ofcosmetics are not subiected to any discoloration while being sterilized;to keep the sterilizing apparatus at an even temperature and at atemperature most suited for a given material; and to provide anarrangement whereby the material shall be iedcontinuously at apredetermined rate, so that the sterilizing chamber shall not beoverfilled at any time. I

It is the further object of this invention to provide an improved methodof sterilizing materials used in the manufacture of cosmetics in whichdefinite currents of compressed air are set up continuously in such amanner that those high speed compressed air currents will tend to removefrom the inner surface of the walls of the sterilizing chamber materialsadhering thereto, thus increasing the efllciencyand thoroughness of thesterilizing apparatus.

It is also an object 01 this invention to provide an improved process inwhich the steriliz-' ing chamber is arranged so that the air inlets diect the flow of co press d ai i t e so e g ge ent wi h one for carryingout the above processes which will be capable oi operating continuouslyat a high rate of output which shall be of simple con-- struction,easily and quickly assembled and disassembled and therefore easy tomaintain in a sanitary condition, and wherein a mixture of materials maybe obtained during sterilization.

The process and apparatus is not however limited to the useillustratively disclosed therein but may be adapted whenever it isdesired to. accomplish the same result and bringing about thedestruction of bacteria and microorganisms in materials used for otherpurposes.

In the accompanying drawings constituting a part hereof, in which likereference characters indicate like parts,

Fig. 1 is a front view of an ing my invention:

Fig. 2 is a side elevational view thereof, some parts being broken awayfor clearness;

Fig. 3 is a view similar to Fig. 2, showing still other parts brokenaway for clearness, and showing the apparatus in a different operativeposition:

'Fig. 4 is a horizontal cross-sectional view taken through thesterilizing chamber;

Fig. 5 is a fragmentary, enlarged, vertical crosssectional view of theapparatus; and

Fig. 6 is a view similar to Fig. 5, but taken from a different portionof the apparatus.

The apparatus comprises the base i having a pair of extensions 2thereon, provided with ribs or tracks 3.' Mounted on said tracks aresets of wheels 4 mounted for rotation on axles 6 held in bearings 8,which in turn are secured to plate 1 constituting part of sterilizingchamber 8. Through this arrangement, the mixing chamber maybe shiftedfrom below the top or I cover 26 when desired, to facilitate cleansingoi the interior of the mixing chamber. A cover plate 9 removably securedto the base i allows access to the interior thereof. a

apparatus embody- A-standard l0 securedto the base I extends upwardlyabove chamber .8 terminating in a horizontal overhanging arm i i withinwhich a vertical screw I 2 is mounted. A beveled gear !3 secured toscrew 12 meshes with similar gear N on horizontal shaft is held inhearing it and terminating in wheel i'l having handles I8 thereon formanual manipulation of the screw H. The screw I2 is threaded intohorizontal arm i9 having a yoke 20 at one end thereof in slidingvertical bar 2!. the opposite end has a depending portion 22 terminatingin pivot 23. A crank'havins' arms 24 and 25 is .mounted on said pivot.Arm 2! is secured to cover 26 of sterilizing chamber 8. Arm 241 has itsfree end beveled an contacts with similarly beveled portion '21 of block28 secured to standard i0. 1 Y

When it is desired to lift the cover 26 from chamber 8, the hand gripsl8 are manipulated to turn the wheel 11, thus turning the screw 12 thusbeginning to raise cover 26. By reason oi the beveled portion 21 and arm24, the upward movement of bar i8 causes a tilting of cover 26, as.shown more particularly in Fig.3. This sterilizing temperature thetemperature thereof being largely dependent upon the materials beingmixed and sterilized, and for this. purpose there is secured to theunderside -of member 1 constituting the bottom of chamber"! remember 81forming an additional chamber. A series of electric-heaters 68 of anysuitable type are secured therein by screws 69 and connection 10 10whereupon arm is is drawn vertically upward,

renders the interior surfaces on cover 26 read-- 3'! and 38 of chamber8, as more particularly shown in Fig. 4. A series of openings 38 in theouter wall of the sterilizing chamber ,angularly' placed, allow thegasentering through openings 35 to pass through the sterilizing chamber ina therefrom lead to a source of electrical energy. Generally, heatingelements 68 are suitably spaced underneath the entire extent of chamber8.

The hoppers 42 may be mounted for movement in order to place them in aposition so that they will not interfere with the lifting of cover 26 asshown in Fig. 3. For this purpose, there are provided a pair of bracketsll having at their extreme ends vertical pivot rods I2 on which aremounted bars I3 which in turn are secured to the bases 43 of hoppers";Set screws are provided whereby upon the loosening thereof bars 13 maybe swung outwardly carrying hoppers 42 with the attached pipes 5|therewith. The cover 28 may be provided with suitable insulatingmaterial as for example, a. layer of cellular asbestos 14 or the like,such insulating material may be provided about the entire cover, ifdeswirling movement. Similar openings 4| in the inner wall of thesterilizing chamber allow gas from openings 38 to pass into thesterilizing chamber with a similar swirling motion tending to uniformlydistribute the currents of gas and material being sterilized.

There .is provided a pair of hoppers." mounted on blocks 43 having ashaft 44 carrying an agitator 45 within the same and immediately belowsaid hoppers. A gear 46 on shaft 44 meshes with gear 41 which is in turnsecured to gear 48 whereby the train of gears may be driven. Shaft 49rotated by gear 41 has a screw conveyor 50 secured thereto for takingmaterial from hoppers 42 and feeding the same into pipes 5i. Said pipescommunicate with feed hoppers 52 allowing material to enter chamber 8 atpoints 53 near the outercircumferenceof said chamber. At the innercircumference of said chamber there is an exit opening 54 communicatingwith separator 55 adapted to impart a cyclone action to- .by the weights62 hold the container 51 in operative position and by the raising ofsaid weights, the said container may be readily removedfor emptying thecontents thereof.

The driving means for gearing 46-41-48} may sired. Briefly, theoperation of the improved apparatus is as follows: 7

The materials to be mixed are delivered into the mixing chamber from thehoppers 42 by the feed mechanism described and more particularlydisclosed in Figs. 5. and 6. As the materials are fed into the mixingchamber, air or other gas under pressure is admitted through pipes 35and 36 into the annular portions 31 and 38 of the mixing chamber. Fromthence the air passes in streams through the angular openings 39, asindicated by the dotted lines in Fig. 4, to swirl the materials roundand round within the cham-- ber 40 and thoroughly mix the same. Duringthe time that this mixing operation is taking place, the temperaturewithin the chamber is maintained at a suitable high level, according tothe be directly connected to the train'as shown in Fig. 5, butpreferably reduction gearing isepro' vided as shown in Fig. 6. A set ofgears G3-.-64 1 is provided on sleeve la-that is loose on shaft 44, thegear filmeshing with gear 48 and gear 64 meshing witlij -"gea'r 55, thelatter'beingjdirectly connected to d ve motor 68. Change speed gearingmaybe provided at this pointL is kept at a suitable sterilizing" chamber8 nature of the materials being mixed and sterilized, so that thematerials being mixed are simultaneously heat-sterilized.,"I'he mixedand heated materials descend through opening 56- and into the container51 while the air or gas under pressure leaves the apparatus through Itherein and a predetermined time elapse, sufficient to give adequatesterilization and then removed from the chamber and separated from thegas used. .Based upon these principles many variations in the actualconstruction both in form and in detail in the apparatus may be madewithin the principles set forth.
